The starters
Airfree Lotus design is unique in many ways. the 7.7 x 13 x 7.7 dimension is relatively short unlike most air cleaners. The weight is consistent at 3.3 lb which means moving it from room to room is a breeze (remember to turn off the air purifier before moving). Inspired by the mysticism of the Lotus flower, the beautiful color light will beam up like flower petals blossoming. Great for home decor or as a night light for children when they are trying through the dark. Air inlet is located at the bottom air convection while air outlet is at top. Carrying around the air purifier is as easy as carrying a laptop thus no issue packing it for travel.
Being a Portugal made product, the build quality is good with no signs of off-gassing. Like all Airfree air purifiers, there is only 1 control and it is for the adjustable night light. You can adjust the light intensity or color via the touch control sensor. Other than that, it is the ultimate form of a plug and play model.
To keep the Airfree Lotus in perfect shape, do not leave it under direct light e.g. at windows or outdoor. Instead, place it indoor and a few feet off the wall or sofa. Make sure the air inlet and outlet are not blocked from airflow distribution. Airfree Lotus is safe for children and pets as it does not emit ions, ozone, or any harmful byproducts back. Just make sure they do not insert their fingers or small objects like a pin, rod, or coin into the vents.
With no other function to talk about, let’s quickly recap on its features. Airfree Lotus air purifier is CARB certified ozone-free with 2 years warranty. It comes with passive safety tech to prevent any short-circuit. This includes Thermistor safety sensors, thermal fuse, tilt sensor, varistor, and current limiting. It will not make the room hotter despite relying on heating elements. Safety-wise, never exceed Airfree Lotus power voltage and only plug to a standalone electrical outlet. Do not use a step-down or step-up transformer to convert the voltage output. If the power plug is damaged, have it replace through an authorized service center. Never attempt to repair or disassemble the air purifier by yourself.
Airflow, speed, and CADR
What’s inside count
Think about it as a bottle sterilizer or but at a higher output. Airfree Lotus patented Thermodynamic TSS technology works in a similar fashion as boiling water. Contaminated air is drawn in through natural air convection. The inner mini-ducts heats the air over 400°F (200°C), killing 99.99% of the allergens and microorganisms like dust mites, pet dander, bacteria, viruses, mold, and pollen in the process. Finally, the air will be cool off inside the machine so only room temperature clean air will be flown back out. The whole purification process is eco-friendly, maintenance-free, emits no ion, and harmful byproducts. According to an independent lab test in Sweden, Airfree Lotus can even reduce ozone by up to 26%. Simply switch it on and you will breathe better as room air quality gradually improved. Great for asthma sufferers or person with severe allergies.
To further demonstrate Airfree Lotus effectiveness, this filterless air purifier has gone through many rigorous real-life scenario tests in ISO laboratories all over the world e.g. Intertek (U.S.), CNAS (China), and INETI Library (Portugal). All the gathered results will be measured before and after the installation of Airfree Lotus.

Keep it down
Without the humming noise from the motor fan, filter-free Airfree Lotus is 100% silent at all speed. The murmuring noise operation is great for all places as it would not disturb your daily activity. This includes working, watching TV, cooking, meditation, or sleeping. Airfree Lotus quiet purification is also perfect for a hospital, dentist, nursery home, and meeting room that values absolute serenity.
Airfree Lotus sterilizing thermodynamic TSS Technology power consumption is relatively low (52 W). This is further enhanced with the auto energy saving mode where the air purifier will shut off its ceramic core once it reaches a temperature peak point. For all-day operation, the average electric cost will be $0.19 dollars per day, $5.7 dollars a month, or $68 dollars a year. Compared with other household appliances like an air conditioner, heater, and TV, Airfree Lotus is significantly lower.
At what cost

Airfree Lotus VS the challengers

Airfree Iris 3000
Cheaper and sharing the same purifying technology, coverage, airflow performance. You do have to give up on the opening flower petal design.
Airfree Onix 3000
Even cheaper with the same performance and TSS filterless technology. The only thing you will have to settle for is a fixed "anti-stress" night light.
Honeywell AirGenius 5 HFD320
Technically a hybrid air purifier with a reusable permanent filter. Choose this if you want a conventional purifying method that traps particles rather than boiling them.
